The vegetal pole of a frog zygote differs from the animal pole in that ______. A. the vegetal pole has a higher concentration of yolk B. the blastomeres originate only in the vegetal pole C. the vegetal pole cells undergo mitosis, but not cytokinesis D. the polar bodies bud from this region

Answer 1

The vegetal pole of a frog zygote differs from the animal pole in that the vegetal pole has a higher concentration of yolk.

After the fertilisation of the egg by the sperm in a frog, three regions are formed in the zygote. These are:

1. Upper animal hemisphere or upper animal pole which shows pigmentation.
2. The grey crescent which is a small area with almost no pigmentation. It is present in between the upper animal pole and the lower vegetal pole.
3. Lower animal hemisphere or lower vegetal pole which is white in color.

Thus, the vegetal pole of a frog zygote differs from the animal pole in that the vegetal pole has a higher concentration of yolk.
